Dimensional Location: The Gravity Falls Universe where Doctor Doom Killed Stanley Pines.

"Well, I can't say that I saw this one coming." Bill Cipher says nervously.

Doctor Doom had Kidnapped Stanley Pines and blasted the Mystery Shack apart.

"The Time Baby has told me all about Bill Cipher and the Mystery Shack Portal, Mister Mystery dies now!" Doctor Doom declared.

"Can't we talk this over?" Stanley Pines asked fearfully.

Bill Cipher watched helplessly as the Mystery Shack was destroyed.

"30 Years getting Stanford Pines to build that Gateway and Doctor Doom destroys it instantly, Curse the Time Baby's Plans!" Bill Cipher proclaimed.

"Maybe if we didn't Trick Stanford Pines into Building Portals for us repeatedly, the Time Baby would not be predicting our every move right now." Another Bill Cipher says from behind him.

"Stop Gloating! The Northwest Mansion is this way!" Bill Cipher yelled back.


Dimensional Location: The Gravity Falls Universe where Bill Cipher and Lord Voldemort went to Hogwarts as children together.

Earth Year: 1940 AD.

The Red Skull stared at Bill Cipher distrustfully.

"The Red Skull! Hydra War Hero Number One! Sign my Autograph Book!" Bill Cipher screamed cheerfully.

"Another Demon Fanboy?" The Red Skull asked disinterestedly.

"The Name is Bill Cipher, I want to help you in exchange for your help building this." Bill Cipher explained.

The Red Skull studied the Triangular Portal Blueprints carefully.

"Do we have a deal?" Bill Cipher asked hopefully.


Dimensional Location: The Gravity Falls Universe where Doctor Doom Killed Stanley Pines.

The Shield Agents swarmed over Gravity Falls.

Wendy Corduroy was still in shock that Dipper and Mabel had been found dead.

The Avengers were even being called to help discover why Doctor Doom destroyed the Mystery Shack.

The Forensics Teams were still studying the wreckage from the Mystery Shack's Destruction.

"Doctor Doom came all the way into Gravity Falls and then just Murders Stanford Pines on sight. I'm thinking this was personal." Tony Stark pointed out.

"Background Checks on Stanford Pines, he was being watched by the Red Skull's Hydra Organization." Captain America added.

"You think that Doctor Doom Killed Doctor Stanford Pines to keep him away from Hydra?" Tony Stark asked suspiciously.

"That answer only makes sense if Doctor Doom really wanted Stanford's Research destroyed." Captain America reminded him.

"Well, Stanford's Hidden Laboratory was found somewhere inside the Mystery Shack's Basement, Nick Fury says the Broken Elevator is slowing him down." Tony Stark admits thoughtfully.
